My parents used to grow asparagus. Every year there would be a couple breeding up against one of the beams of the barrack? where we would cool and sort. They came about the same time as the asparagus, round about 6 weeks before the 24 of june or when the birches where growing leaves
I haven't seen many yet, but think, if we wouldn't use plastic to stimulate the growth as is done nowadays, we wouldn't have asparagus yet either. It is still early in season and the nights are very cold.
They might still come
